COBRA Continuation Coverage Guide
The Consolidated Omnibus Budget Reconciliation Act requires employers with 20 or more employees to offer continuation of group health coverage to qualified beneficiaries who would otherwise lose coverage due to certain qualifying events. COBRA compliance involves strict notice timelines, precise premium calculations, and careful administration of election and payment processes. Failure to comply can result in excise taxes of $100 per day per affected beneficiary, ERISA penalties, and exposure to litigation. This guide covers the essential requirements every employer must understand.
COBRA Qualifying Events and Coverage Duration
COBRA is triggered by specific qualifying events that cause a loss of group health plan coverage. For employees, qualifying events include voluntary or involuntary termination of employment for reasons other than gross misconduct, and a reduction in hours that results in loss of coverage eligibility. These events entitle the employee and covered dependents to up to 18 months of continuation coverage.
For spouses and dependent children, additional qualifying events include the death of the covered employee, divorce or legal separation from the covered employee, the covered employee becoming entitled to Medicare, and a dependent child ceasing to meet the plan's definition of eligible dependent. These events entitle the affected spouse or dependent to up to 36 months of continuation coverage.
A second qualifying event occurring during an existing 18-month COBRA period can extend coverage to 36 months for spouses and dependent children. Additionally, qualified beneficiaries who are determined to be disabled by the Social Security Administration within the first 60 days of COBRA coverage are entitled to an 11-month extension, bringing their total coverage period to 29 months. The employer may charge up to 150 percent of the applicable premium during the disability extension period.
Notice Requirements and Timelines
COBRA imposes notice obligations on both the employer and the plan administrator. When a qualifying event occurs due to termination or reduction in hours, the employer must notify the plan administrator within 30 days of the event. The plan administrator must then provide the COBRA election notice to each qualified beneficiary within 14 days of receiving the employer's notice. In practice, many employers serve as their own plan administrator, collapsing these two steps into a single 44-day window.
For qualifying events that the employer may not be aware of, such as divorce, legal separation, or a dependent aging out of coverage, the qualified beneficiary is responsible for notifying the plan administrator within 60 days of the event. If the beneficiary fails to provide timely notice, the plan administrator has no obligation to offer COBRA continuation coverage for that event.
The initial COBRA election notice must contain specific information prescribed by COBRA regulations, including a description of the qualifying event, identification of the qualified beneficiaries, an explanation of their rights, the deadline for electing coverage, and instructions for making premium payments. The Department of Labor provides model election notices that satisfy these requirements, and most employers use these templates as the foundation for their notices. Using an outdated or incomplete notice creates compliance risk even if coverage is offered on time.
Premium Calculation and Payment Rules
Employers may charge COBRA-qualified beneficiaries up to 102 percent of the applicable premium for their coverage. The applicable premium includes both the employer and employee portions of the premium, plus a 2 percent administrative fee. For self-insured plans, the applicable premium must be calculated using one of two methods prescribed by COBRA regulations: the actuarial determination method or the past cost method, which bases the premium on the plan's actual costs during the prior plan year.
Qualified beneficiaries have a 45-day grace period from the date of their COBRA election to make their initial premium payment, which must cover the period from the date of the qualifying event through the current month. After the initial payment, subsequent monthly premiums must be paid within 30 days of each monthly due date. The plan cannot terminate COBRA coverage for non-payment until the applicable grace period has expired.
Premium rates for COBRA beneficiaries must reflect the same coverage they had as active employees, and the rate must be the same as what the employer would charge similarly situated active employees if they were paying the full premium plus the administrative fee. If the employer changes plans or premium rates during the COBRA coverage period, the COBRA premium adjusts accordingly. Employers should communicate any rate changes to COBRA beneficiaries in advance to avoid confusion and payment delays.
Election Process and Administration
Qualified beneficiaries have 60 days from the later of the date they would lose coverage or the date they receive the COBRA election notice to elect continuation coverage. Each qualified beneficiary has an independent election right, meaning a spouse or dependent child can elect COBRA even if the employee does not, and vice versa. Beneficiaries may also elect different coverage options if the plan offers multiple levels of coverage.
Once COBRA is elected, coverage is retroactive to the date of the qualifying event, ensuring no gap in coverage. This retroactive coverage means the employer must accept and process claims incurred between the qualifying event and the election date once the initial premium is paid. Providers and pharmacies should be advised that COBRA coverage may be retroactively activated.
COBRA beneficiaries are generally entitled to the same benefits, choices, and services as similarly situated active employees. If the employer adds new plan options or benefits during the COBRA period, COBRA beneficiaries must be given the opportunity to enroll. Likewise, COBRA beneficiaries participate in open enrollment on the same terms as active employees, allowing them to change plan elections annually.
State Mini-COBRA and Compliance Considerations
Many states have enacted their own continuation coverage laws, often called mini-COBRA statutes, that apply to employers with fewer than 20 employees who are not subject to federal COBRA. These state laws vary significantly in their requirements, including covered qualifying events, duration of coverage, premium limits, and notice timelines. Some state mini-COBRA laws provide longer coverage periods than federal COBRA, and in a few states, the state law applies alongside federal COBRA for employers with 20 or more employees, potentially extending coverage beyond the federal maximum.
Compliance with COBRA requires careful coordination between HR, payroll, benefits administration, and legal counsel. Many employers outsource COBRA administration to a third-party administrator who handles notice generation, premium collection, payment tracking, and termination processing. Even when COBRA is outsourced, the employer retains fiduciary responsibility and should regularly audit the TPA's performance, including notice timeliness, accuracy of premium calculations, and proper handling of qualifying events.
Maintain detailed records of every qualifying event, notice sent, election received, and premium payment for each COBRA beneficiary. Federal regulators and courts look closely at the timeliness and completeness of COBRA notices when evaluating compliance disputes, and the burden of proof falls on the employer to demonstrate that proper procedures were followed.
